ohcres, the r ,Y iety-V eduction action. :ill or .subite Haring th ns described my invention, what i cleiin as new tho/reim and desire to secure by Letters Patent, isv i. ihc process of obtaining ammonia, which consists in reacting upon cyenarnid with at; ueous huid in the proportion of not less than three molecules or' water to two atoms ont the nitrogen present in the cyanemid ut :i ternpereture above 100' centigrade subst'entially as set forth.

f2. The process et' obtaining ammonia., which consists in reacting upon cyanamid with equiv ous huid in the proportion of not less then `three molecules of water to two atoms of the nitrogen present in the cyana. id, et a temperature ot' not less then 200'O centigrade, and in presence ot' carbonio-acid gas, substantieliy and 'for the purpose .set forth.

3. 'Ehe process of obtaining ammonia;y hich consists in reacting u pon cyanarnid with aqueous iuid in the proportion of not icss than three molecules et water to two atoms of vthe nitrogen present in the eyanamid at a teml perature not less than 1000 centigrade, and effecting the reaction und er pressure, substantielly and for the purrioses set forth.

i rJLhe process of obtaining ammonja,which consists in reacting upon cyanamid with aqueous fluid in the proportion of not less than three molecules of water to two atoms of the nitrogen present in the cyanamid at atemperature of not iess than 10()C centigrade, and in presence of carbonio-acid gas and effecting the reaction under pressure, substantially as and for the purpose set forth.

e. The process of obtaining ammonia,whch consists in boiling eyanarnid with aqueous fluid in the proportion of not less than three molecuies of water to two atoms of the nitrogen present in the eyanamid, whereby formiates re obtained in solution, substantially as and for the purposes set forth.

6. The process otobtaining ammonia,which consists in reacting upon cyanamid with steam in the proportion of not less than three molecules of water to two atoms ofznitrogen present in the oyanamiol, atatemperature of about 300@ eentigrade, whereby formiates of the metals bound in the carbid used in the pr0 duction of the cyanamid are also obtained, substantially as set forth.

in testimony that I claim the foregoing as my invention l have signed my name in pres*- ence of two subscribing witnesses.
